Meanwhile, the blowing and suction machine has the advantages of simple and reliable structure and low cost.
Description
Technical field
The utility model relates to a kind of blower that is used to blow, inhale foreign material such as leaf, belongs to a cleaning type garden equipment, particularly relates to a kind of blower with air inlet valve structure.
Background technology
The scope of application of blower is extensive, is applicable to family's cleaning, highway maintenance construction, lawn and gardens cleaning etc.Present common blower on the market adopts air inlet runner side by side and goes out flow channel; The air inlet port of air inlet runner is located at grade or close together with the gas outlet that goes out flow channel basically; When blower was operated in blow mode, air inlet runner had bigger relative wind velocity unfavourable balance with the intersection that goes out flow channel, forms eddy current easily; Wind is made an uproar big and is influenced air blowing efficient, does not also have corresponding techniques to solve this problem at present.
Summary of the invention
To the deficiency that above-mentioned prior art exists, the utility model aims to provide a kind of blower with air inlet valve structure, with the blower that solves prior art wind when the blow mode make an uproar greatly, the inefficient defective of blowing.
The technical scheme of the utility model is following:
A kind of blower with air inlet valve structure comprises head and the airduct that is connected the head front end; Described head comprises casing, is provided with motor, fan blade, the switching mechanism of pressure-vaccum function and dust mouth in the casing; Described airduct comprises aspiration channel and blower, and aspiration channel constitutes air inlet runner, and blower constitutes and flow channel; It is characterized in that: the end at described air inlet runner is provided with an air inlet port, and described air inlet port is provided with a movably air inlet valve, and when blower was operated in suction mode, air inlet valve was with inlet close; When blower was operated in the blowing mould formula, air inlet valve was with air inlet open.
Further; Described air inlet port is arranged on the side near the casing of air inlet runner terminal position; Also be provided with at least one chute on the side of described casing, described air inlet valve is provided with at least one sliding muscle, and what described sliding muscle slided is installed in the chute.
Further, be provided with seal felt between described air inlet port and the air inlet valve.
The effective effect that the utlity model has is: in the time of can solving blower and be operated in blow mode; The blowing mouth air-flow mutual interference mutually of the inlet scoop air-flow of aspiration channel and blower, the easy problem that forms eddy current; Can effectively reduce wind and make an uproar, improve air blowing efficient, have characteristics simple and reliable for structure, with low cost simultaneously.

Fig. 2 is the structural representation of the head of the blower that relates to of the utility model.
Fig. 3 is the structural representation of the air inlet valve that relates to of the utility model.
Fig. 4 is a side schematic view of the air inlet valve among Fig. 3.
The specific embodiment
As shown in Figure 1; The hand-held blower of the utility model comprises head 1 and the airduct 2 that is connected head 1 front end; The inside of head 1 is equipped with a motor and fan blade (not shown), and fan blade is installed on the motor output shaft, produces working air current through the rotation of driven by motor fan blade.Also be provided with a pressure-vaccum function-changing device (not shown) and dust mouth 4 in the head 1, be used for said blower is set in blowing mould formula or suction mode.
Described airduct 2 comprises aspiration channel 5 and blower 6, and described aspiration channel 5 has an inlet scoop 13 and an air outlet 14, forms air inlet runner between described inlet scoop 13 and the air outlet 14; Described blower 6 has an air intake 15 and blowing mouth 16, forms out flow channel between described air intake 15 and the blowing mouth 16.
Shown in Fig. 1 to 4, when being operated in the blowing mould formula in order to overcome blower, the air-flow that goes out at the inlet air flow at 13 places, inlet scoop and blowing mouth 16 places disturbs each other; Even formation eddy current; Reduce wind simultaneously and make an uproar and improve air blowing efficient, the utility model is provided with an air inlet port 7 at the end of described air inlet runner, and described air inlet port 7 is provided with a movably air inlet valve 8; When blower was operated in suction mode, air inlet valve 8 cut out air inlet port 7; When blower was operated in the blowing mould formula, air inlet valve 8 was opened air inlet port 7.
Preferably; Described air inlet port 7 is arranged on the side near the casing 3 of air inlet runner terminal position; Also be provided with at least one chute 9 on the side of described casing 3, described air inlet valve 8 is provided with at least one sliding muscle 10, and what described sliding muscle 10 slided is installed in the chute 9.
In order to increase the tightness between air inlet port 7 and the air inlet valve 8, between air inlet port 7 and air inlet valve 8, be provided with the seal felt (not shown).
The course of work of the blower of the utility model is following:
When the pressure-vaccum function-changing device is set in suction mode with blower; Working air current is drawn into foreign material such as leaf, chip the fan blade place of head 1 through air inlet runner through the inlet scoop 13 of aspiration channel 5; After smashing through fan blade; Under the effect of working air current, the foreign material after smashing are sent to the dust mouth 4 that is arranged on the casing 3, be discharged to through dust mouth 4 in the collection container that is connected on the dust mouth 4; When the pressure-vaccum function-changing device is set in the blowing mould formula with blower; Air inlet valve 8 is opened air inlet port 7; Air will directly enter into the inlet air flow runner from air inlet port 7 and form working air current; Working air current gets into blower 6 through the air intake 15 of blower 6, forms out entraining air stream, and the blowing mouth through blower 6 blows out then.
Air inlet valve structure through the utility model; Blower is operated in when the blowing mould formula, does not almost have air to be inhaled into air inlet runner through the inlet scoop 13 of aspiration channel 5, thereby has effectively avoided the air-flow at inlet scoop 13 and blowing mouth 16 places to form interference; Can significantly reduce wind and make an uproar, improve air blowing efficient.
Other undeclared parts that the utility model relates to are identical with prior art.
